You stood at the bottom and worked the whole thing out. Left hand there, right foot up, cross through. You had it. Then you got on, made two moves, and the plan was gone.

That is not a bad memory. It is a full one. Working memory holds about four to seven things, you tried to store twelve, and the extras fell out somewhere around move three. Route reading is a skill with a known bottleneck, which means it has a known fix.

How do I actually read a route?

By remembering fewer, bigger things. Instead of twelve individual moves, find three sections and name each one: big moves to the volume, compression to the rest, technical sequence to the top. Three items fits comfortably in memory, and each one triggers the moves inside it once you are there.

This is what experienced climbers are doing when route reading looks effortless. They are not holding more information than you. They are holding less of it, in bigger pieces.

What am I missing when I read?

Rests, almost always. Previewing is threat detection, so your attention goes to the hard section and you build a map of a route made entirely of difficulties. Then you climb it at one pace with no stopping points, and arrive at the crux with nothing left.

The other thing is that rests are rarely jugs. They are body positions: a stem, a knee bar, a straight arm, a heel hook, somewhere you can stand up. If you are scanning for a big hold you will walk straight past all of them.

• Straight Arms in Climbing
  A straight arm is a skeleton hanging rather than a muscle working, which is what makes it a rest.

What do I do when the beta turns out to be wrong?

Holds look different from below. A crimp that seemed incut is flat, a sidepull is really a sloper, and the reach is longer than it looked. That is not a reading failure, it is unavoidable, because you are seeing everything in profile from underneath.

What is avoidable is having only one plan. Strong route readers carry two or three ways through a crux even though they will use one, which is what lets them adapt on the wall instead of coming down to start again.

Where to go next

Reading tells you what to do. The rest of your climbing decides whether you can do it. If your sequence keeps being right and you keep falling off anyway, the limiter is somewhere else.
